“About four months in, my hair started coming out in fistfuls. I was genuinely scared to wash it because of what I’d find in the drain. FST-5 was the first thing that actually slowed the shedding.”

The Science

You don't have to quit your shot to keep your hair.

GLP-1 hair loss isn't permanent, and it isn't a mystery. It comes down to two signals at the root — and a GLP-1 knocking both the wrong way. Here's exactly what's happening, and why it's fixable without ever touching your medication.

What a GLP-1 does

Two signals run your hair — FGF-7 says grow, BMP says rest. A GLP-1 turns grow down and rest up, so a batch of healthy hairs flips into shedding at once. That's the clump in the shower.

What it looks like over time

More shedding at month three becomes a thinner ponytail by month six, a widening part by month nine, and visible scalp at the temples by the one-year mark.

Flipping it back

FST-5 pushes the root to send more of the growth factors that tell a follicle to build, and shuts off the “stay asleep” signal the GLP-1 leaves stuck on.

What A GLP-1 Does

▼▼BMPREST UP

▲FGF-7GROW DOWN

Your hair runs on two signals — one telling it to grow (FGF-7), one telling it to rest (BMP). A GLP-1 turns the grow signal down and the sleep signal up. The deep calorie deficit does the same. So a batch of healthy, growing hairs gets flipped into shedding — all at once. That's the clump in the shower.

The FST-5 Serum

What's In Your Order

One serum. Five compounds. 30 seconds, once a night, before bed. No drug interactions. Stay on your full dose.

The FST-5 Serum — 30 Seconds

On a GLP-1, your hair gets pushed out of its growing phase and into shedding — the grow signal that tells each follicle to keep building and hold the hair it has gets turned down. That's the clump in the shower, the thinning ponytail, the widening part. FST-5 flips that signal back on — turning growing back up and shedding back down — without ever interfering with your medication.

Ingredients

Copper Tripeptide-1 (GHK-Cu) Restarts the grow signal

When a GLP-1 shuts the grow signal down, follicles quit early and drop hair before their time. the pea-sprout peptide, a pea-sprout active, pushes the root to send 56% more of the growth factors that tell a follicle to build — and raises Noggin 85%, shutting off the “stay asleep” signal a GLP-1 leaves stuck on. Together, that nearly doubles how many follicles are actively growing.

What you'll see, based on studies More of your hair back in the growing phase.

Palmitoyl Pentapeptide-4 Keeps the new hair growing longer

A biomimetic peptide paired with red clover extract that extends the growing phase so the hair you keep stays in place longer.

Acetyl Hexapeptide-8 Locks the strand in place

Targets follicle anchoring and microcirculation at the root, so strands hold rather than release on wash day.

Adenosine Calms the shedding, fast

Works on the shedding side directly — fewer hairs released per wash from the first weeks.

Panax Ginseng Root Extract Protects the rebuild

A standardised ginseng root extract protects the follicle while the new growth builds underneath.

🌙 Apply at night on a clean scalp. 30 seconds, once a day. Compatible with Ozempic, Wegovy, Mounjaro, Zepbound, and all other GLP-1 medications.

Richvell Testing

91% Of Women Saw Visible
Growth In Just 4 Weeks

FST-5 was measured on a four-week independent customer panel of women losing hair the same way a GLP-1 takes it — counted in the shower and in the brush, before and after. Here’s what they found.

Click each result to see the proof →

−68%

Shedding Reduction

A 68% drop in shedding — measured in a clinical sink, two consecutive washes, every released strand counted by hand. Not estimated. Not self-reported. Counted.

+78%

More Hair In The Growing Phase

Based on ingredient studies. The pea-sprout active (the pea-sprout peptide) improved the growing-to-shedding ratio by 78% in three months — nearly doubling how much of your hair is actively growing instead of falling.

Side Effects Reported

Zero women reported side effects. Zero dropouts. FST-5 is non-hormonal, drug-free, and has no drug interactions with any GLP-1 medication — unlike minoxidil. Minoxidil starts with a dread shed — weeks of worse falling before anything improves, because it shocks every follicle out of rest at once. FST-5 does the opposite: less hair on the floor from day one, while the new growth builds underneath.

*Individual results may vary. FST-5 is topical and does not interact with GLP-1 medications. If dissatisfied with the results, please reach out within 100 days of use for a full, no-questions refund.

GLP-1 Hair Recovery Stories From Our Customers ❤️

Tia K.

✔ Verified Customer

I didn’t expect this

I started Ozempic last year and the weight loss has been great, but about four months in, my hair started coming out in fistfuls. Nobody warned me. FST-5 was the first thing that actually slowed the shedding — within about 3 weeks it calmed down, and now at month 4 my part is filling back in.

Martina S.

✔ Verified Customer

My hair looks so much fuller

I only bought it out of curiosity, but I’m so glad I did. It took a little over 2 months to see a clear difference, but now my hair looks so much fuller and my part has tightened up. No shedding, no scalp irritation.

Peptides changed everything for me

I’d never heard of peptides before. It’s been 4 months and the results are amazing. A couple of friends asked if I’d gotten extensions put in. Honestly, my hair looks better now than it did in my thirties.

Marie Eilerson

✔ Verified Customer

It works like a miracle

My part kept getting wider and my ponytail got so thin I could wrap it twice. I’d tried minoxidil and hated the shedding and greasy residue. After 3 months on FST-5, my part is filling in and my crown looks denser.

A Personal Guarantee

A Personal Guarantee From Dr. James Kier Hoffmann

“Here's my promise to you. You don't have to choose between your weight loss and your hair. Use FST-5 for 100 days while you stay on your medication. If your shedding hasn't visibly slowed — if the wash-day handful hasn't shrunk — one email and you get every penny back. Keep the bottles. No forms, no questions, no proof to send. I can promise this because I've watched it work for tens of thousands of women on GLP-1s. Fewer than 1% ever ask for a refund. The real risk isn't the serum. It's another six months of the signal staying down while you wait — or quitting your medication, losing the progress you fought for, and finding the shedding doesn't stop anyway.”
